JOSEPH STABMAN, OF CEDAR RAPIDS, IOWA, ASSIGNOR TO NORTH STAR MANUFAC-TURING COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

CELL-CASE MACHINE.

To all whom it may concern Be it known that I, JOSEPH citizen of theUnited States, residing at Cedar Rapids, in the county of Linnand Stateof Iowa, have invented certain new and useful Improvements in Cell-(JaseMachines, of which the following is a specification.

This invention relates to automatic machines for manufacturing suchfillers as are used, for example, in egg-cases.

The primary object of the invention, generally stated, is to increasethe output of machines of the class referred to.

Egg-case fillers as ordinarily constructed are composed of intersectingstrips of paper, the strips being cut from a web unwound from a roll,and the strips having slots punched therein so that they may beinterlocked. In the machines heretofore used, a single web has beenpassed through the punching and shearing mechanism, said mechanismacting only upon the downstroke. The machine herein shown comprises adouble-acting punching and shearing mechanism combined with means forpassing two webs through said mechanism,

STARMAN, a

the latter acting upon one web during the up-stroke and upon the otherweb during the down-stroke, whereby the capacity of the punching andshearing mechanism is doubled.

-In machines heretofore employed, all or a portion of the mechanism forassembling the filler strips have had a reciprocatory or intermittentmovement, the shock caused by the frequent and sudden stoppage andstarting of the movements of the parts having materially limited thespeed at which the entire machine may be run.

It is a feature of my invention to employ only continuously rotatingparts for assembling the strips, whereby the speed at which the machinemay be operated is greatly increased.

The machine hereinafter described comprises continuously rotatedassembling devices which may be driven at high speed and areci'procatory punching and shearing mechanism which, by reason of beingdouble-acting, is adapted to serve the highspeed assembling mechanismwithout being itself actuated at excessively high speed.

Another object of the invention, as applied to a machine havingv anendless series Specification of Letters Patent. Patented Sept 26, 19 [6.Application filed January 6, 1911.

Serial No. 601,149.

of forms, is to improve the means for givmg the forms a quarter-turn,whereby backlash is prevented and slippage of the filler strips in theforms obviated.

A further object of the invention is to improve the means for ejectingthe completed fillers from the forms.

The invention also relates to construet onal features contributing todurability, simpllcity and compactness of the machine, and ease ofadjustment for wear or for variations in the condition of the paper.

In the accompanying drawings, Figure 1 is a side elevation of acell-case machine embodying the features of my invention.

Fig. 2 is a top plan view of the machine.-

Fig. 3 is a vertical sectional view taken in trates a brake for certainfeed rolls comprised in the machine. Fig. 7 is a section through thepunching mechanism on line 7 of Fig. 1. Fig. 8 is a longitudinal sectionthrough the parts shown in Fig. 4. Fig.

9 1s. a view in top plan showing the web being fed into the rotary stripconveyer. Fig. '10 is a vertical central section, through said conveyeralong the line 1-0 of Fig. 1. Fig. 11 illustrates the operation ofinsert ing the first series of strips into the form. Fig. 12 representsthe operation of interlocking the transverse series of strips with thefirst-mentioned strips. Fig. 13 is a plan view of the completed fillerindicating the points at which the ejector engages the filler during theejecting operation. Fig. 14 is a fragmental view of one of the stripscomposing the tiller. Fig. 15 illustrates a portion of the endlessseries of forms, and the mechanism for ejecting the completed fillersfrom the forms.

A cell-case filler is ordinarily composed of fourteen strips ofstrawboard or like material, the strips being about 2} inches wide andabout 11-; inches long. One series of having been placed'in the form,the latter' is turned through a quarter revolution and a series ofstrips I) placed across the first mentioned strips, thus completing thefiller.

The embodimentherein shown of the invention comprises an endless seriesof forms arranged centrally of the machine, means at one end of themachine for punching and severing strips a of the first series, meansfor feeding webs of paper to said punching and severing means, means forconveying the punched strips to a point adjacent the path of the seriesof forms, means for transferring the strips from said conveyer to theforms, and similar means at the other side of the series of forms forproducing strips 6 of the other series from paper webs and for conveyingsaid strips to and intermeshing them with the strips a.

In the illustrative embodiment herein shown, the framework of themachine comprises two side frames, 1 and 2. A main shaft 3 (see Figs. 2and 7) is rotatably mounted in suitable bearings in said frame and in abracket 4. Fixed to said drive shaft is a drive pulley 5 and a bevelgear 6, the latter meshing with a similar gear 7 which is fixed upon oneend ofa shaft 8 extending longitudinally of the machine and supportedfrom the frame member 2. A s ur gear wheel 9 meshes with a pinion 10 seeFigs. 1 and 2) fixed upon a worm shaft 11 supported in bearings upon theframe member 2. A worm 12 (Fig.3) upon the shaft 11 meshes with a wormwheel 13 fixed upon a transverse shaft 14. The latter shaft ispreferablymounted for vertical adjustment, as by providing the shaft with bearingboxes 15 arranged within recesses 16 in the frame members 1 and 2, saidboxes being supported at the proper height by means of screws 17threaded into said boxes and bearing against the top and bottom walls ofsaid recesses. 18 are look nuts for locking the *screws-in adjustedposition. A shaft 19 is supported in the framework directly above theshaft 14 and parallel therewith. Preferably the shaft 19 is .supportedfor vertical adjustment, and may be provided with adjustable bearingboxes 20 as in the case of the shaft 14. There is provided a suitabledriving connection between the shafts 14 and 19 as, for example, avertical shaft 21 supported in bearings upon the side frame member 1,

said vertlcal shaft being connected to the transverse shafts 14 and 19by means of bevel gears 22." The shafts 14 and 19 support the endlessseries of forms hereinbefore referred to. In the present illustrativeembodiment, a chain wheel 23 is fixed upon each of said shafts, saidchain wheels carrying an endless chain 24. The forms are rotatablymounted upon said chain. In this instance each form consists of a squaresheet metal tray 25 provided upon its rear side with a strengtheningframe 26, the trays beingpivoted to the chain by means of supports 27and pivot studs 28 (Fig. 11). Each tray bears a series ofstrip-supporting devices consisting in this instance of pairs of fingers29 30 (Figs. 1, 3 and 11), there being seven rows of eight pairs offingers in each row, the rows of fingers being 1% inches apart. Thefingers 30 are of thin spring metal and are adapted to hold the stripsbetween said fingers 30 and the fingers 29. While passing up one side ofthe conveyor and down the other, the forms are guided to move in astraight line, and are prevented from turning, by means ofrails 31, 32,33 34 fixed in the framework in the machine at opposite sides of thepath of the forms, the end portions of said rails being curved toconform to the path of movement of the forms when passing around thechain wheels 23.

The means for giving the forms a quarter turn before said forms begintheir downward movement and before they begin theirwith the segments 36.As a form pames aroundthe upper chain wheel 23 the projection 37 on thesegment 35 strikes the end of the rack 39, and, as the chain continuesmoving, the form is swung through a quarter revolution on its pivot 28,the segment meshing with the rack during such movement. The quarterrevolution thus imparted to the form turns the filler strips a from thehorizontal position which they heretofore occupied intoa verticalposition, ready to receive the transverse or second series of strips 6.When said second'series of strips has been interlocked with the firstseries of strips, and the form has reached the lowest point in itstravel, and the completed filler has been ejected from the form,

thp latter is turned into position to receive another set of fillerstrips a, such turning being accomplished through the medium of thecurved rack 40, the projection 38 and the segment 36.

In the present embodiment two strips on are inserted into the form atone time, and two strips b are likewise inserted at a time. The tworolls of paper from which the strips a are formed may be supported inany suitable manner, as, for example, upon a rack 41 locatedconveniently to the righthand end of the machine (Figs. 1 and 5). Thetwo webs unwound form the rolls of paper extend between two'feed rolls42 and 43 (Fig. 8), the lower roll being journaled in bearing boxes 44which are adjustably mounted in guides 45 by means of screws 46. Theupper roll is' likewise journaled in boxes slidable in the guides 45 andis pressed downwardly by coiled springs 47 (Fig; 4). The upper roll maybe raised to release the webs by means of a cam 48 loose on one of thejournals of the roll 43 and provided with a handle 49 and arranged tooperate against a portion 50 of the adjacent bearing box for the lowerroll.

The upper roll 43 is driven in this instance by means of a sprocketchain 51 extending over sprocket wheels 52 and 53 fixed upon the shaft 3and a journal of the upper feed roll, respectively, (Figs. 7 and 8). The

lower roll is positively driven by means ofa gear connection 54 55(Figs. 2 and 4) with the upper roll. After passing through the feedrolls 42 and 43, the'two webs pass over the guide olls 56 and 57 andthrough guideways 58 (Fig. 8) to pairs of feed rolls 59 60 and 61 62.The feed rolls 59 60 61 62 are journaled in bearing boxes 63 (Fig. 4)which are adjustable in guides 64 in the framework. The bearing boxesfor the feed rolls 59 and 62 are held in adjusted position by means ofadjustable screws 65, and the rolls 60 and 61 are held against theircompanion rolls by means of a spring 66. The two pairs of feed rolls 5960 and 61 62 are driven alternately by means herein shown as comprisinga gear segment 67 pivoted at 68 and meshing with pinions 69 (Fig. 2)rotatably mounted upon the journals of the rolls 59 and 62. Fixed toeach of said pinions is an arm 70 (Fig. 4) carrying a pawl 71 72adapted. to engage diametrically opposite teeth formed in collars 73 74fixed to the journals of the rolls 59 and 62, the pawls 71 72 facing inopposite directions so that upon the upward movement of the gear segment67 the lower set of feed rolls is driven, while upon the downwardmovement of the gear segment the upper pair of feed rolls is actuated.The

gear segment may be swung by any suitable means; that herein shown byway of example comprises a lever 75 pivoted at 76, one end punchings.

of said lever having pivoted thereto a rod 77 that extends looselythrough a stud 78 rotatably connected to the gear segment 67. Collars 79are adjustably fixed upon the rod 77 at opposite sides of the stud 78 bymeans of set screws 80. It will be seen that the collars 79 may besecured upon the rod-77 close to the stud 78 or at a greater or lessdistance from said stud, to regulate the extent of movement of thesegment and thereby the extent of each feed One end of the lever 75 isconnected by means of a pitlfian 81 to a face plate 82 on the shaft 3.Said face plate has an undercut groove 83 therein (Fig. 7) to receivethe T-head of the wrist pin 84 for the pitman 81. Said Wrist pin issecured in place by means of a nut 85. It will be seen that the wristpin 84 may be fixed at the desired dlstance from the center of the faceplate 82, and thereby impart to the lever 75 the desired amplitude ofoscillation.

To prevent overrunning or other casual movement of the feed rolls .59 6O61 62, I

provide a brake of any suitable formgfor the rolls 59 and 62, as, forexample, the brakes 86 actlng upon the journals of said rolls.

The two sets of feed rolls 59 60 and 61 62 alternately advance the websinto a punching mechanism comprising in this instance a stationaryframework 87 in which are fixed two stationary die plates 88 89 (Fig. 7)each pro ided with a stripper plate 90 91, the die plate 88 beingsupported above the die plate 89. A cross-head 92 is arranged betweensaid die plates and carries punches 93. The cross-head is guided bymeans of guides 94 and is fixed to guide rods 95 which are slidablymounted in openings 96 in the framework 87. Eccentrics 97 are fixed uponthe shaft 3 the straps 98 of said eccentrics having internally-threadedsockets 99 to receive screw-threaded rods 100 which are pivoted to yokes101 connecting the lowerv ends of the guide rods 95 at opposite sides ofthe machine. Fixed to the inner edge of movement of the webs.

the cross-head 92 are two knife blades 102 and 103 adapted to coact withstationary shear blades 104 to sever the webs as the latter arealternately fed forward by the feed rolls 59 60 and 61 62. It will beseen i that the punch and shearing mechanism acts upon the upward aswell as on the downward stroke, thus utilizing a movement heretoforelost in cell-case machines of the prior art.

The material punched from the webs finds an exit through the passages 87which may be connected, if desired, to'an exhaust air system (not shown)for withdrawing the The meansfor conveying the strips a from thepunching and shearing mechanism to the mechanism that inserts saidstrips into the form comprises a shaft 105 (Fig. 10) lo position for thenecessary tatably mounted in bearing boxes 106 which are adjustable inguides 107 fixed to the frame members 1 and 2, the boxes being securedin adjusted position by means similar to that employed for the bearingsof the shafts 14 and 19. The shaft 105 is continuously rotated by meansto be hereinafter described. Fixed-upon said shaft are seven disks 108,

which are spaced apart by means of collars 109. Upon each of the collars109 is mounted a cam disk 110 held from rotation by means of an arm 111connected by a link 112 to a cross-rod 113. The cam disks 110 areadjustable, each being held in position by means of a bolt 114 extendingthrough the arm 111 and through an elongated opening in the link 112(Fig.1). The adjustable mounting of the shaft 105 and the cam disks 110permits of the making of such adjustments as may be necessitated bywear, changes in the condition of the paper, etc.

Each of the disks 108 carries upon one face and adjacent to itsperiphery an annular series of bell cranks 115 each pivoted at 116 toits disk. One arm of each bell crank carries a pair of spring fingers117 adapted to'receive a filler strip a, while the other arm of the bellcrank carries a roller stud lying within a cam groove 118 in theadjacent cam disk 110. The set of finger-carrying disks 108 is arrangedbetween the shearing mechanism and the ascending side of the endlessseries of forms, the fingers 117 receiving the strips at the shearingmechanism and carrying them down and around to a point opposite theascending forms. It will be understood that if the fingers were rigidlysecured 'tothe disks 108 in a radial position, the

outer ends of said fingers would be quickly carried out of position toreceive the strip. I therefore pivot the pairs of fingers 117 upon thedisks 108, as heretofore described, and provide the cam disks 110 tosuitably modify the movement of the fingers, the cam groove in saiddisks 110 being of such form that the outer ends of the fingers remainopposite the point of discharge of the strips long enough for said stripto be fed there into by the feed roller and before 'the strip is severedfrom the web by the shear. As

shown in Fig. 8, the fingers swing downwardly out of ,a radial positionas the fingers approach the receiving position. When the outer ends ofthe-fingers reach the receiving position, the fingers swing upwardly asthe disks 108 continue turning, such upward movement being justsufiicient to compensate for the continuous movement of the disks and tomaintain the fingers in receiving ength of time. As shown in Fig. 8, onestrip at a time is fed into the fingers 117. The portion of the camgroove ad acent to the form is of such shape as to bring two rows offingers 117- carrying filler strips directly opposite and into alinementwith two rows of fingers 29 30 u on the form, as shown in Fig. 11. Asthe orm and the disks 108 continue moving, the fingers 117 swingdownwardly sufiiciently to keep the outer ends of the fingers 117opposite the fingers 29 30 long enough to permit of the transfer of thestrips from the conveyer fingers to the form fingers.

The means for removing the filler strips from the fingers 117 andpressing them into oppositely disposed rows of fingers upon the formsconsists, in this instance, of six fingers 119 of spring steel or othersuitable mate rial, fixed upon a rock shaft 120 in the framework andextending in the spaces among the disks 108 and 110. The fingers 119 arearranged to be swung to push the filler strips out of the fingers 117into the fingers 29 30 by means herein shown as comprising a crank arm121 fixed t0 the rock shaft 120, a crank arm 122 fixed upon a shortshaft 123, a rod 124 connecting said crank arms, a crank arm 125 fixedto said shaft 123, a shaft 126 in the supporting frame, an eccentric 127upon one end of said shaft 126, a rod 128 connecting the crank arm125"with the eccentric 127, sprocket wheels 129 and 130 fixed upon theshafts 3 and 126, respectively, and a chain 131 extending over saidsprocket wheels.

The means for forming, feeding and inserting the stri s b comprisedevices at the opposite side 0 theseries of forms substantiallyidentical with the described devices for forming, feedin andinsertingthe filler trips 0, as indicate% in Fig. 1. The filler strips 6 arecarried upward and over from the shearing mechanism to a positionadjacent to the descending formsfand are there pushed onto the strips aso as to interlock therewith, by means of fingers 132 similar to the.fingers 119. While the strips are bein inserted into the fingers 117and while said strips are being interlocked with the strips on the form,the movements of 110 said fingers are modified, as described inconnection with the fingers 117, to compensate for the continuousmovement of the parts. The fingers 132 are fixed to a rock shaft 133which is rocked by means of a crank arm 134 and a rod 128* connectingsaid crank arm to an eccentric 127 upon a shaft 126.

The completed fillers c are ejected from the forms by means to 'be nowdescribed, reference being had to Figs. 3 and 15: A shaft 135 issupported in bearings which are preferably adjustable, said shaft beingdriven in this instance from the shaft 21 by bevel gears 136. A bracketor framework 137 is loosely suspended from said shaftso that it mayswing or .yield, as will hereinafter appean- A shaft 138 is rotatablysupported in the framework 137, and has cranks 139 fixed to its ends.Slidably mount- 130 ed in guides 140 on the framework 137 are rods 141which are connected by yokes 142 and pitmen 143 with the cranks 139. Tothe lower ends of the rods 141 are fixed lates 144 from which pins 145project ownwa-rdly. The shaft 138 is intermittently rotated throughsuccessive complete revolutions by means of a Geneva stop motionconsisting of a disk 146 fixed on the shaft 135, said disk carrying twodiametrically opposite rollers 147 adapted to enter the four radialslots in the star wheel 148, the latter being fixed upon a shaft 149carried by the framework 137. The shaft .149 is connected to the crankshaft 138 by means of a spur gear wheel 150 and a pinion 151.

Each of the trays 25 has openings 152 (Fig. 3) therein for the receptionof the ejector pins 145 as the latter are projected downwardly to pushthe completed filler 0 out of the form: Said openings are somewhatlargerin diameter than the pins 145 to provide clearance. The pins engage thefiller at the intersections of the strips 0. and b as shown in Fig. 13.When a form bearing a completed filler reaches substantially theposition shown in Fig. 15, the pins 145 are rapidly projected downwardlythrough the form and as rapidly elevated, the continuing movement of theform causing the framework 137 to swing a slight distance to the right.When the pins 145 have been withdrawn from the openings 152 theframework swings to the left under the action of gravity into its normalposition, such position being determined by cushions 153 of leather,wood or other suitable cushioning -material fixed to the framework inposition I to contact the shaft 14.

The two sets of conveyer disks are rotated by means of a sprocket wheel154 (Fig; 3) fixed on the shaft 135, a sprocket wheel 155 carried by theshaft 105 of the disks for the strips (1, a chain 156 extending aboutsaid wheels, sprocket wheels 157 158 fixed to the shafts 105 105*,respectively, and a chain 159 running over said wheels 157 158.

160 and 161 are idlers to take up slack in the chain belts 156 159.

The operation of the machine will be apparent from the foregoingdescription, and need not be here set forth;

I have herein described one embodiment of the invention withconsiderable particularity without intending thereby to limit theinvention to the details set forth. It is obvious that the constructionof the several mechanisms and their relative order or arrangement may bevaried by those skilled in the art without departing from the spirit ofthe invention, and that various features may be used apart from others.
